Groundworks holds a 4.9-star rating across 566 Google reviews and specializes in mold remediation for Manchester homeowners. Given that Manchester averages 72% relative humidity and gets around 42 inches of rain yearly, mold problems aren't uncommon here - especially in older homes. If you're dealing with visible mold or a musty smell, it's worth getting a professional assessment rather than trying to handle it yourself.
Before you call, know that New Hampshire doesn't require a specific mold remediation license, so you'll want to verify that any contractor you hire is registered with the NH Office of Professional Licensure, carries IICRC certification, and has appropriate insurance. A typical remediation project in the Manchester area runs between $1,500 and $4,650 depending on the scope. Ask Groundworks to explain what they found, show you the affected areas, and provide a clear breakdown of their treatment plan before you commit to anything.
